ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented Sept. 5, 1905.

To a whom it um/y concern:

Be it known that I, EDWIN MILLER MoG EE, a citizen of the United States,and a resident of Yankton, in the county of Yankton and State of SouthDakota, have invented a new and Improved Acetylene-Generator, of whichthe following is a full, clear, and exact description.

This invention relates to certain improvements in acetylene-gasgenerators providing for a reliable automatic carbid-supply and insuringautomatically closing the various valves in communication when thecarbid-chamber is open to replenish the charge.

Various other features of major and minor importance are involved andall will be fully set forth hereinafter.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the complete apparatus. Fig. 2 is an endelevation of the same with parts broken away. Fig. 3 is an enlargedsection showing the carbid chamber and the valve. Fig. i is a sideelevation of the carbid-valve and the adjacent parts, and Fig. 5 is adetail section on the line 6 6 of Fig. 4.

10 indicates the water-chamber, having a neck 11, on the upper end ofwhich is mounted the carbid-chamber 12. Said chamber is provided with aclosure let to permit filling the same and with ascrew-cap 15,surmounting the closure.

16 indicates the gas-holder, which communicates with the neck 11 by agas-conveying pipe 11.

17 indicates a vent-pipe from the chamber 10 to the atmosphere by way ofthe pipe 17, with which latter pipe the pipe 17 communicates in anydesired manner. This pipe 17 is commanded by a valve 18.

19 indicates the pipe for filling the chamber 10 with water. This pipeis provided with a valve 20.

The valves 18 and 20 are connected by a stem 21, provided with an arm orhandle 22 to facilitate the operation of the valves and by means ofwhich the valves 18 and 20 may be simultaneously opened or closed.

23 indicates a funnel or receiver, so as to facilitate pouring of thewater into the pipe 19.

The arm or handle .22 is embraced by a loop 2% on a rod 25, so that uponthe operation of the handle the rod is moved up or down. Said rod isprovided at its lower end with an offset 25, engaging the handle of avalve 26, which is intended to permit withdrawing the water and theresiduum from the chamber 10. By means of the rod and the connections asshown the handle 22 moved to operate the valves 18 and 20, and theoffset 25 serves when the valves 18 and 20 are closed to hold the valve26 against opening movement. \V hen, however, the valves 18 and .20 areopen and the rod 25 raised, the valve 26 may be opened manually. The rod25 extends upward and is provided with an inwardly-directed horizontalbend 27, passing over the top of the chamber 10, and from this point therod again extends vertically through a suitable guide 28 to a pointlevel with the carbid-chamber 12, where the upper extremity is bentinward and downward, as indicated at 29, so as to engage the closure 14kof the carbid-chambcr.

30 indicates a handle connected to the cap 15 and adapted to facilitatescrewing and unscrewing the closure.

As best shown in Figs. 3, 1t, and 5, the carbid-chamber 12 has adischarge-spout 31, commanded by a swinging valve 32. This valve issupported by swinging arms 33, suitably mounted in the neck 11 and oneof which is connected to a rocking operating-shaft 34. 32 indicates anupward projection on the valve 39', which serves the double purpose of astop to limit the valve movement and an agitator for the earbid.indicates an internrediatcly-fulcrumed latch for holding the valve 32 inclosed position. This latch has one arm longer than the other, and saidlonger arm drops into active position by force of gravity, as shown inFig. i. The short arm of the latch is connected with a rod 36, whichextends up into the carbid-chamber, and when the cap 15 is in place therod is pushed downward by the cap, thus lifting the long arm of thelatch into inactive position and allowing the operation of the valve.\Vhcn, however, the cap is removed, the latch automatically drops intoactive position and further operation of the valve is prevented. Therocking operating-shaft 3a is mounted in the lower part of thecarbid-chamber and in the neck 11 of the chamber 10, the shaftprojecting beyond said neck and carrying two arms 37 and 38. Of the armsthe arm 37 is engaged in a loop 39, formed on a feed-rod 40, and the arm38 is designed to coact with a projecting arm or rod 41, carried by therod 25. The feedrod 40 is mounted to run in a guide 12, attached to thetank or holder 16, and is attached by abraoket 43 to the bell 1 1 of thegas-holder. hen the bell 4A is in raised position, as shown by dottedlines in Fig. 2, the arms 37 and 38 will be thrown up, as the dottedlines illustrate, and the valve 32 will be moved into closed position,as shown in Fig. 4. Assuming, however, that the cap 15 is in place, thelatch 35 will be' kept raised in inactive position, and then as the gasis withdrawn from the holder and the bell 44L drops the down wardmovement ofthe feed-rod 4:0 and loop 39 will allow the arm 37 to dropinto the position shown by full lines in Fig. 2, this arm then carryingwith the arm 38 the shaft 34 and the connected valve, thus moving thevalve to open position; as shown by full lines in Fig. 2. Carbid willthen be fed from the chamber 12 into the tank or chamber and gas will begenerated in the usual manner. The gas passes out into the gas-holderthrough the pipe 11", again raising the bell and moving the valve intoclosed position. It is in this manner that the general operation of thegas manufacture is automatically carried on.

If it be desired to refill the carbid-chamber, the rod 25 should belifted by the arm 22, thus allowing the closure 14 to be lifted manuallyfrom its position. This upward movement of the rod 25 and arm 22 throwsthe valves 18 and 20 to open the vent-pipe 17 from the chamber 10 to theatmosphere and to open the water-inlet pipe 19. Simultaneously theoffset 25 will disengage the valve 26 to permit the opening of the valveand the withdrawal of the water and residuum of previous operations fromthe chamber 10. Then the valve 26 should be closed and the tank 10 andcarbid-chamber 12 refilled. After this the closure may be placed inposition, thus allowing the rod 25 to move downward and thereuponreturning the arm 22 and valves 18 and to their normal positions. Itwill be observed that this downward movement of the rod does notnecessarily open the valve 32, the opening of this valve beingcontrolled by the feed-rod 40. The 'upward movement of the rod 25,however, necessarily lifts the arm 38 and through the same closes thecarbidvalve.

Various changes in the form, proportions, and minor details of myinvention may be resorted to without departing from the spirit and scopethereof. I consider myself entitled to all such variations as may liewithin the scope of my claims.
